['.A L'CULATING-MACHINE.

Application filed December 14, 1907'.

To all iti/mln 'it m ag/ confer/i Be it known that I. FRANZ Tnixks, engineer, subject ot'- the Emperor of Germany. residing' at Brunswick, Duchy ot' .lrunswick, llmpire ot' Germany, have invented certain new and usei'ul Improvements in Caleulatirig-Machines, ot' which the following is a specification.

This invention relates to calculating machines having two crank revolution counting mechanisn'is t'or registering the rotations of the hand crank. l-`undamentally this type of machine is disclosed by British latent No. 13,70() of 1890, and the present machine is an improvement on that disclosed by the latter patent,

Essentiallythe invention consists in `uniting; the motive power o'l' two crank revolution counting' mechanisms, and also in the use ot' the dual counting` mechanisms. (lne of these mechanisms may be disposed on the carriage of the machinevand the other disposed in the upper part ot the casing, or both mechanisms may be disposed in the upper part ot' the casing. One oi these cank revolution counting' mechanisms is provided with well known tens transferring means, and the counting mechanism thus equipped may be employed in simplified multiplication and subtraction operations as will be more fully hereinafter explained.

The invention further consists in the details of construction and arrangement, ot the Several parts which will be moreI tally hereinafter specified.

The mechanism embodying the presenty invention has been devised to obviate disadvantages and inconveniences incident to machines o t' this class as heretofore constructed.

The improved ,organization embodying the present features of the invention is shown in preferred form 'in the accompanying drawings, and in the latter:

Figure l 1s a rear view of the machine, the upper part of the rear Vall and the adjusting mechanism being removed, the main counting mechanism beingI cove-red in this iigure by the unbroken portion otl the rear Wall. Fig. 2 is a cross section taken on the line 2 2 of Fig. l and showing in detail the driving` parts for the revolution counting mechanism. Fig. 23 is across section on the line 3-3 of Fig. l.

Serial No. 406,442.

Aln the drawings, Fig. 3, each of the well known cam disks u is arranged adjacent to an adjusting' wheel Iw, both the cam disks and adjust-ing.wheels being; liXed on the. common sha t't j, the cam disks when rotated bringing' the radially displacable teeth fc oi the adjusting wheels into and out ot operating position. rotated by a projection or handle u projectinge` through a slot Il in the casingr cover and exteriorly engageable. lt will be understood that a suitable number ot the cam disks and adjustable wheels having'` the radially displaceable teeth will be employed and the number of slots u will correspond to the number oi.j cam disk handles or operating devices u. The adjusting wheels when rotated by m'eans ot the machine crank l1. and the intermediate spur gear wheels zt transmit their movement by means of gear wheels fw', 1N to the figure wheels fw* ot' the main counting mechanism, the said latter mechanism being mounted on a displaceable carriage 1/ movable parallel with relation to the axis i so that the teeth o ot' the adjusting wheels may act on the gear wheels lze ot the higher ligure wheels uit, for instance, the tens or hundreds ligure wheel. The main counting.mechanism is also provided with well known tens transterrineY means as disclosed in Letters latent No. 975,180, granted to 111e November 8, 1910, and consisting ot' pivoted levers af operated by pins w3 of th'e tigure wheels to* so as to bring a beveled face ai in position for engagement with a pivotal tooth ol the adjusting wheel and thus set up engagement between the latter and the gear wheel fw. The beveled face a." forms a partof the upper extremity ot' each pivoted lever fr, and two of the teeth o and two beveled faces afioim a part of the Complement of each lever a". and each wheel L04 to accommodate right and left hand rotations of the machine crank L. Beveled faces o2 are provided on the peripheries of the adjusting wheels to bring the tens 'transferring levers c back into their positions of rest or in normal eon dition.

ln the present machine, two crank revolution countinjsY mechanisms are embodied and tho object. and function ot' the same are t'ully in Letters latent No. 955.3505.

975,180, grantedr to me November S. 'lilith The counting mechanism, which has no llach ot' the cam-disks is CIK " tens transferring means, is the usual rev- 'being differentiated by coloring the same.

llo calculate in au abbreviated. manner, a crank revolution count-ing mechanism with tens transli'erring means 1s required. ln

order to satisfy all commercial demands it' is necessary' that a calculating machine of this type be 'provided with two crank revolution mechanisms, one with tens transferring means and the other without said trans'- ferring means.

rhe two crank revolution counting mechanisms a and Z1 are located within the upper part oit the machine fusing above the adjusting mechanism and on the same axis c, and the driving member for each counting mechanism, namely, single toothed wheels c and f are coupled to each other by means of a sleeve g and to which the said teeth and f are secured. The sleeve g is movable or displaceable axially on a shaft Z rotated through the medium of spur gears if, Ze from the crank 7i in such manner that the shaft- Z makes a full. notation simultaneously with the crank Zt.. means of an endless band or chain a running' over two pulleys a located at opposite er;- tremities of the machine, the upper part of the chain 'n being connected to an arm 'in held at its lower extremity by a shaft mf, see lP ig. 3, and having' a fork mi2 at its upper extremity to engage between circumferential shoulders y on the sleeve g, see Fig. l, and the lower part ot the chain a is coi'inected to an arm s in turn securedto and moving with the main counting mechanism carriage v/,see lfig. llhcn the carriage 3,/ is moved laterallv one value distance, that is to say, the distance from one ligure disk to to the next, or greater distances, both teeth or tappets e and f ot the crank revolution counting inech anisms c and Zi are moved simultaneously one or more value distances laterally, but in an opposite direction so that both teeth. or tappets e and are always brought in position to engage the correctteeth o, Zi ot the respective crank revolution counting mechanisms o; and Z when the machine crank /i is turned. rlhc counting mechanism a, shown by Figs. l and 3, is provided with well known tens transferring means, consisting of a lt'ltaltese cross disk Z and two gears Z and (Z2 respectively engaging a single tooth ot a ligure disk c ot one value and the tooth of a next higher figure disk a., as clearly shown hy Fig. l. rthis tous transferring means or mechanism is well known The sleeve g isdisplaccd by in this class of machines, and the h'laltese cross disk Z and gears CZ cZE are arranged on a common shaft, as (Z3, see Figs. l and 3.

All of the groups of gears and the Maltese crossdisks are loosely arranged on the said shatttZ, the Maltese cross disks being disposed between the gears Z and (Z2 of each group and rigidly connected therewith and formed with a series of peripheral notches which cooperate with the adjacent counting disks, and said notches are equal in number to the teeth of the gears associated therewith. rkt intervals the gears (Z and Z2 and the Maltese cross disk Z are secured against rotation and at other times rotation ot' these parts ensues when a transfer ot one value to the next higher value is to be effected. rlfhe operation of this weil known tens translterring means as above specified' is clearly disclosed in my copending application Serial Number 378,854, tiled June 13, 1907.

To render the machine practicable it is ohvious that means must be provided to disengage the tens transferring means without interfering with the counting disks a representing higher values than the one or more et such disks that may have been operated. lfor this purpose each tens trans- -ferring device (Z, d, (Z2 is held by a forked two-armed lever o which swings on the axis o and is influenced by a spring 02 so as 'to hold the tens transferring means or transterrer in engagement with the counting disk gearing. A slidahle or displaceable bar 03 located adjacent the lower extremities of the levers 0 locks the latter against disengagement during the tens transferring operation and is notched as at o4 to permit release and -svvingingout movement ot' one lever 0 at a time for unlocking the counting disk a next higher than the similar disk which has been operated. riihc operating means for the bar o3 is clearly disclosed in my Patent No. 975,180, hereinbetore referred to, in a corresponding part indicatedlby the numeral (58 in said patent, and the operation of this bar is therefore well known, 'llhe disengagement ot the tens transferring devices is .effected hy means ot' a cam r connected to the sleeve (j and rotatable with the teeth or tappets e and .lhis cam r moves uniformly with the sleeve g on the shaft Z so as to regularly coincide with each transferring device and press the same outwardly and consequently release the tens transferrer means cooperating with each counting disk a in accordance with the general operation of the machine.

The shattc ot the crank revolution counting mechanisms is provided with a cam. disk y) to operate in conjunction with a lever q fixed on the sha'l't o and whereby, during the operation ot bringing thegure disks hack into zero position, allv the tens tansit'crring means or transtcrrers (Z, (Z, (Z2 are si- `multaneously swung outwardly, the free end 'as Well as disposition in places other than those specifically described may be adopted without in the least modifying the mecha..

nism other than obvious duplication or variation in the dimensions and proportions.
